Thanks EJCC; I'll keep all that in mind.
No problem!
In a moment of complete silliness, I accidentally gnawed on an ESTJ's arm.

What should I do?

That is so adorable! Did the ESTJ react well? Was it awkward? 'Cause if it wasn't awkward, then you don't need to do anything
What were you like growing up?
I'm becoming fairly certain I'm raising an ESTJ little girl, and I'm wondering what another one was like

One of my best friends is an ESTJ as well, so I'm looking at commonalities and all that good stuff!
Hm... Not sure if all of these apply, but here are some of the characteristics I had as a child:
- Most of the time, either in a generally friendly/genial mood or really really hyper (i.e. not whiny, not cranky, but a very happy kid overall)
- Not exactly "tomboyish" per se, but interested in guy-dominated hobbies, and friends with more guys than girls
- A "good kid"; never got in trouble, was never "grounded", always did well in school, generally didn't challenge authority unless the authority was being "unfair", or unless the authority wasn't as knowledgeable on a particular subject*
- Kind of a know-it-all
- Assertive, blunt, and pretty arrogant
- Occasionally very creative (within limits)
- VERY loyal to friends, and even more so to family (had a sense of duty even at a young age)
- Afraid of new things, and unwilling to step out of comfort zone
- Tendency to take things personally
- Lots and lots of Enneagram 1 characteristics (especially the need to make excuses for every single thing done wrong)
- Easily embarrassed (e.g. "Crap! I should NOT have said that. SUCH a mistake!")
- Prone towards outbursts of anger (sometimes involving hitting people**, but most of the time not)
- Not so good at saying goodbyes, or apologizing to people
- Tendency to accidentally offend people
- Mature; often better at interacting with adults than with other kids*** and very good at sucking up to teachers (not intentionally sucking up to them, but being nice to them and getting on their good side, and as a result being a bit of a teachers pet and not as well-liked by fellow students for that exact reason).
Etc. Can't think of anything else at the moment, but that should be good for starters
*If a teacher spelled something incorrectly on the board, I would, on occasion, run up to the front while they weren't looking and correct their spelling. OR I would just raise my hand and correct them that way.
**If I were a boy, I'm certain that I would have beat kids up if I were mad at them. If I weren't raised by such a nice family, I'm sure I would have been a bully.
***Adults were more likely to get my sense of humor
